unescapeHtml

Turns the five HTML entities that escapeHtml produces back into the characters they stand for.

Entity	Becomes
&	&
&lt;	<
&gt;	>
&quot;	"
&#39;	'

The string is walked once, not replaced five times in a row. Turning & into & first and < into < afterwards would read < as <, where it has to come back as the literal text <.

Only these five entities are recognised, so anything else — ',  , ', a numeric entity — is left exactly as it is. unescapeHtml(escapeHtml(text)) therefore always returns the original text.

Parameters
